JOHN I'IOEY, OF SAN FRANCISCO, CALIFORNIA.

BED-BOTTOM.

SEEQIFICATION forming part of Letters Patent No. 663,171, dated December 4, 1900.

Application filed June 14, 1900. Serial No. 20,246. (No model.)

To (all whom it may concern:

Be it known that L'JOHN HOEY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Bed-Bottoms; and I hereby declare the following to he a full, clear, and exact description of the same.

My invention relates to improvements in bedbottoms in which an elastic woven netting is stretched upon a framework; and it consists of the parts and the construction and combination of parts hereinafter described and claimed.

Figure 1 is a plan of the bed-bottom looking up from underneath. Fig. 2 is a longitudinal section.

In the manufacture of bed-bottoms in which a woven-wire netting is employed these nettings are usually connected with the ends of the framework of the bed-bottom; but the distance between the ends is so considerable that it has been found necessary to reinforce this class of mattresses by various supplemental supports. Longitudinal elastic twisted-wire cables have been frequently employed for this purpose and have been ex tended from the ends of the frame beneath the woven-wire mattress in various Ways, so as to lend additional support thereto. I have found, however, that the great strain brought upon the frame by connecting all these tension devices with the ends thereof will'cause the frames to warp and twist, so that the corners will often rise or be depressed diagonally and the frame will be twisted out of shape and will not lie straight upon the bed.

It is the object of my invention to overcome these difficulties by dividing the strain be tween the end rails and the side rails, and this I effect by using a series of cables extending from one side rail to the other and having endwise elasticity, and means by which the tension of these cables can be increased by drawing the central portions of two contiguous cables toward each other transversely of their length.

As illustrated in the present drawings, A A are the end and B B the side rails of a mattress-frame.

The woven-wire mattress 2, which forms the bottom, is secured to the end rails and stretched from one end to the other and has no attachment to the side rails, the elastic ribs 3, which extend through this fabric from end to end, assisting in giving it stiffness along the edges and through the center and also making it ornamental.

In my invention I secure the spirally-wound longitudinal elastic cables lto the side rails B at points intermediate between the ends. In the present case I have shown two pairs of these cables, each pair located between the center and one end, and but a little distance from the central line between the ends of the mattress. Each of these pairs of cables is connected by links 5, and these links serve to draw the cables of either pair toward each other after the ends have been attached to the side frame B, and thus increase the tension transversely to the length of the mat tress to any desired degree and froinindependent supports, so that while the mattress itself has a tension acting upon the end rails A of the frame these supplemental cables have a transverse tension from the side rails and at proximately right angles to the mattress itself. These pairs of cables, of which there may be two or more, are disposed beneath the central portion of the mattress, where the greatest weight is brought upon it, and besides adjustably connecting the two cables of a pair I may also connect the pairs together by links 7 of any description, so that they are all united, and any movement in the direction of the length of the bed would be transmitted to all of the cables in unison. By this means I divide the strains between the end and side rails and resist any tendency of the frame to twist or warp out of shape.

If found desirable and to prevent too great a transverse strain upon the side rails of the mattress, I may fix the transverse bars 8 from one rail to the other, preferably at points intermediate between the ends and the center of the frame.

It will be understood that the connectinglinks between the pairs of cables may be made IOO ous Ways by which adjustments of length are made. I do not desire to limit myself to any particular form for these adjustments.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

An improved bed-bottom including a rigid rectangular frame, a fabric connected with the end bars of the frame and unconnected with the side bars thereof, means for reducing the strain of the fabric upon the end rails and dividin said strain between the end rails and side rails consisting of elastic cables extending transversely across from one side rail to the other beneath and in contact with In witness whereof I have hereunto set my hand.

JOHN HOEY.
